It already uses the functions you recommend.

What else do you think a DWIM comment function should
base its behavior on, if not if the region is or
isn't already comments?

Ah, I recognize this from somewhere else, namely

(defun sort-whole-lines (start end)
  (interactive "r")
    (let ((s (progn (goto-char start) (line-beginning-position)))
          (e (progn (goto-char end)   (line-end-position))) )
      (sort-lines nil s e) ))) ; [1]

With comments for some reason, I never felt the need
to do it. But it should make sense, because when do
you ever want to [un]comment say lines, a, b, and c,
and then HALF of line d?
